Watercress care requirements
water
Requires consistently wet or waterlogged soil—essentially mimicking shallow stream conditions. Keep roots submerged or in perpetually moist soil. Standing water or hydroponic systems work well.
soil
Prefers sandy or silty, well-draining soil with high moisture retention. Can also grow in gravel or hydroponic media. Rich organic content is beneficial but not essential; watercress tolerates poor soils.
light
Partial shade to full sun; prefers 4–6 hours of direct light. Too much intense sun can stress the plant; dappled light is ideal.
